Title: Precise Estimation of Source Parameters Using Distributed Acoustic Sensing Data in Central Shikoku, Japan Authors: Takumi Takahashi1,2,*, Aitaro Kato2, Ji Zhang2, Kentaro Emoto3 , Masanao Shinohara2 1Department of Earth and Planetary Science, The University of Tokyo. 2Earthquake Research Institute, The University of Tokyo. 3Institute of Seismology and Volcanology, Kyushu University. *Corresponding author: Takumi Takahashi Description of the Data for the evaluation: time.tar.gz: Arrival times of seismic waves identified from DAS-recorded waveforms. The final number represents the event ID. hdf5.tar.gz: DAS waveforms at the time of the earthquake. The data file spans 30 seconds from the time shown in the filename. station.tar.gz: Location data of DAS stations. Column 2: station number, column 3: latitude, column 4: longitude, column 5: elevation. event.dat: Event list based on the JMA catalog and template matching. Time in the data is Japan standard time (JST).
